The median SAIDI they reported was 45.4 minutes per customer including major event days; the median among all Iowa utilities reporting was 85.7.
The Census Bureau estimates the county's population at 9,525. EIA does not publish customers by county, so which utility serves a given address has to be confirmed with the utility or the state utility commission.
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Figures are for each utility's whole Iowa operation; EIA publishes nothing at county level.
